2, 2, 4, 6, ?, 10, 8, 14, 10
Option 1: 6
Option 2: 5
Option 3: 8
Option 4: 7
Correct Answer: 6
Solution :
Given:
2, 2, 4, 6, ?, 10, 8, 14, 10
Here,
Every alternate term starting from the first is a multiple of 2.
2 × 2 = 4; 2 × 3 = 6 ; 2 × 4 = 8; 2 × 5 = 10
Every alternate term starting from the second is obtained through multiplication with odd numbers.
2 × 3 = 6; 2 × 4 = 8; 2 × 5 = 10
So, the series becomes → 2, 2, 4, 6, 6 , 10, 8, 14, 10
Hence, the first option is correct.
